ED STATES ATENT ROAD- -RUT CUTTER.

SPECIFICATION forming part of Letters Patent No. 488,185, dated December20, 1892.

Application filed January 9, 1 89 2.

To all whom iv may concern:

Be it known that I, ORRIs OULVER, a citizen of the United States,residing at Grand Rapids, in the county of Itasca and State ofMinnesota, have invented a new and useful Road- Rut Cutter, of which thefollowing is aspecification.

This invention relates to road rut cutters; and it has for its object toprovide a machine of this character which is adapted to cut ruts in theground or in the ice for lumber work or any place where heavy loads aredrawn on sleds, and the primary object of the same, to attain this end,is to have the cutting apparatus of the same so disposed as to readilycut out a round rut to receive the runners of the sleds and which willnot clog or turn when the same meet obstacles, but readily run overeverything, plow out the ruts and throw the dirt or ice out of the wayto each side of the machine.

WVith these and many other objects in view which will readily appear asthe nature of the invention is fully understood, the same consists inthe novel construction, combination and arrangement of parts hereinaftermore fully described, illustrated and claimed.

In the accompanying drawings ;-Figure 1 is a perspective view of a roadrut cutter constructed in accordance with my invention. Fig. 2 is adetail transverse section through one of the runners in advance of therut cutting knife. Fig. 3 is a similar view through one of the gageshoes. Fig. 4 is a detail in perspective of the main rut cutting knife.Fig. 5 is a similar view of the advance cutter.

, Referring to the accompanying drawin gs A, A represent the oppositeparallel runners having the rounded bearing edges or traveling upon thesurfaces that are cut, and said runners are spaced and braced apart bythe crossbraces B securely fastened to the top edges of each runner andare of a width according to the width of road to be formed. An ordinaryplatform may be located upon the top runner frame over said braces and asuitable load placed thereon according to the hardness of the ground orother surface to be cut, said platform being secured to the sled framein the ordinary manner. The said $erial No. 417,552. (No model.)

runners A have the forwardly extending reduced ends 0 projecting beyondthe front ends of the runners and connected at their outer ends by thepivoted cross-bar D to which is secured the draft pole or tongue E towhich is hitched the team to draw the machine. The front ends of therunners A are beveled and concaved as at a from the outer faces thereofto the inner and at an angle so as to form a sharp edge a upon theinside of said runners. Closely secured to the runners and fittingaround and projecting forward from the inner and bottom edges formed bysaid ccncaved bevel at the forward ends, are the main cutting knives F.The said rut cutting knives F are made of cast steel and sharpened ontheir top and inner edges so that the wear will always be in the samedirection as their sharpening, and the same will thus be preserved frominjury and sustain longer usage than usual. The knives F have thestraight inner cutting portions f, that are secured at an angle to theinner faces of the runners and project beyond the inner sharpened ends athereof and slanting downwardly and rearwardly from near the top edgesof said runners are curved at their lower extremities to form asemi-circular grooved cutting portion f conforming to the rounded bottomedges of said run hers and encircling and projecting beyond the extremeforward ends of the same and are secured at f upon the outer faces ofsaid runners near the lower edges thereof. It can be readily seen thatas the machine moves in a forward direction the advance knives F willfirst bury their grooved cutting portions f into the surface to be cutand dig out a rut of a rounded shape adapted for the reception of saidrunners, while the inner straight cutting edge of said knives projectingupwardly and forwardly at an angle from the semi-circular cuttingportion f, will cut out and line up the inner sides of the opposite rutsand cut and remove all obstacles, of a cutable nature therein, whilemoreover at the same time the bevel of the forward ends of the runnerswill serve to throw the cut material scooped by said knives away fromthe runners.

To carry off the ice, ground, or mud and other material removed from thecut ruts, mold boards G are secured to the outer faces of each oppositerunner directly in rear of the rut cutting knives F. The said moldboards G are provided with a front downwardly inclined receiving ledgeg, and the straight rear walls g which serve to carry the material awayfrom the runners of the machine to any distance desired according to thelength of said mold board, which are secured to said runners at anoff-standing angle, being analogous to the disposition of mold boards inother plowing implements. Advance cutting knives H are secured to theoutside faces of the forwardly extending ends 0 of said runners anddirectly in front of the cutting ends thereof. The said advanced cuttingknives H are'secured to said ends at an angle corresponding and parallelwith that of the straight cutting sidesfof the knives F which aresecured upon the opposite faces of the runners, and by said dispositionof the straight knives II it will be apparent that while the same loosenup the surface to be cut in advance of the rut forming knives, at thesame time the said knives will cut, mark out and line up the outer sidesof the ruts to be out while the knife portionsf will do the same to theinner sides of the ruts.

To the extreme forward ends of the'projectingends C are secured thedepending plates I extending below the ends 0 and adapted to receive thefront ends of the gage runners J pivotally secured at j betweeneach'pair of plates and extend rearwardly to a point just in advance ofthe rut cutting portions of the knives F, and said gage runners are alsoprovided with rounded edges j which allow the same to travel smoothlyupon the ground and the same are also-provided with the socketed bearingplates K secured upon the top edges thereof near the rear ends of thesame and adapted to receive the ends of the threaded arms N by means ofwhich the screw may be.

manipulated to press the gage runners J downward in order to have themachine cut a small depth of rut or by loosening the same allows themachine to cut as deep a rut as possible according to the nature of theground or use to which the road-way is to be placed.

The construction and operation of the herein described road rut cutteris 110w thought to be apparent without further description.

Having thus described myinvention, what I claim and desire to secure byLetters Patent 1s 1. In a road rut cutter, the combination of therunners having forwardly extending ends, curved rut cutting knivessecured to and projecting beyond the front ends of said runners, advancecutting knives secured to the outer sides of the forwardly extendingends in advance of said rut cutting knives, mold boards secured at anangle to the outer faces of the runners in rear of the front endsthereof, and adjustable gage runners located directly in front of therut cutting knives at one side of the advance knives, substantially asset forth.

2. In a road rut cutter, opposite parallel runners having forwardlyextending ends, curved rut cutting knives secured to and projectingbeyond the front ends of said runners, gage runners or shoes pivoted tothe front ends of said forwardly extending runner ends, and means foradjusting said pivoted gage runners or shoes, substantially as setforth.
